First off, welcome to the forums.

A windshirt is used to block the wind from coming through your fleece jacket or as a layer over your long sleeve shirt. It is usually some what water resistant but not the equivalent of a rain jacket. It weighs a few ounces. I have a Marmot Hydrogen and throw it in with my gear if the weather warrants.

As for tents, check out the REI, Campmor, MooseJaw, Backcountrygear (use the links from this forum) and compare different models. Or, if you want light weight, watch the sale forum here and you might pick up a tarp tent relatively inexpensively. Another option would be to try a hammock. That can be done relatively inexpensively. The weight will be similar, but for me it is much more comfortable.

If you have any other specific questions, just let us know.
